List a newsletter's community

The people who joined this newsletter's community on Commune, most recently joined first. Needs audience: read. Every field on a row is a field the same person's own public profile carries, plus the day they joined.

A roster of people, not a census of the audience. A newsletter that brought its list over from another provider holds subscriptions that are an address and nothing else, and none of them is here: there is no person to name. So the length of this collection is a floor under the community and is never the newsletter's subscriber count. The list to reconcile against a provider is GET /newsletters/{newsletter}/subscribers, which returns addresses.

Only people who are currently subscribed are returned. There is no parameter for asking about anybody else.
